ABSTRACT:
In a measurement device for contactless determination of the rotation angle and/or rotation speed, a disk is fastened on a shaft so as to be fixed with respect to rotation relative to it. During the measurement process, layers of material with good electrical conductivity which are arranged on one or both opposing sides of the disk are moved relative to receiver coils located on opposite sides of the disk (16a and 16b). The measurement device can work according to the eddy current measurement method, as well as according to the inductive method. In order to compensate for measurement errors, the conductive layers are arranged at approximately equal distances (a, b) between two coils. In addition, the greatest possible quantity of measurement points can be used for forming an average.
